Research on Yunnan TV Earthquake Early Warning Information Release

In order to broaden the distribution channels of Yunnan earthquake early warning（EEW）information and better serve the vast number of users, we proposes the overall framework design scheme of the Yunnan TV EEW information release system based on the original TV broadcast system of Yunnan Mobile, Yunnan Telecom and Yunnan Unicom. According to the publishing principle, the MQTT protocol, HTTP protocol and JSON format are selected as the data interaction format between the early warning information release platform and the set-top box or the broadcast control backend. Then the data interaction format is combined with the location information of the set-top box or user information to realize the Yunnan TV EEW information release. After comprehensive testing, the compatibility of the set-top box, the timeliness and reliability of the system have been verified.
